Poinsettia plant named &#39;fismillerl&#39;

ABSTRACT

A new and distinct Poinsettia ‘Fismillerl’ particularly described by the combined features of uniform, red bract color; medium to large sized inflorescence, ovate bracts, uniform, dark-green foliage, ovate leaves almost without lobes; relatively vigorous growth, medium to tall, upright plant habit; and very early flowering response.

Latin name of the genus and species of the plant claimed:

Euphorbia pulcherrima Wild. ex Klotzsch

Variety Denomination:

Fismillerl

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Poinsettia plant botanically known as Euphorbia pulcherrima WilId. ex Klotzsch, and hereinafter referred to by the variety denomination ‘Fismillerl’.

‘Fismillerl’ was discovered by the inventor, Hubert Sumser, from an naturally occurring mutation in the variety ‘Fismille’ ( U.S. Plant Pat. No. 13,660). ‘Fismille’ is characterized by large, bright red colored bracts, dark-green foliage almost without lobes, upright and moderately tall plant habit, and early flowering time.

‘Fismillerl’ was discovered among a group of potted plants of ‘Fismille’ growing in a greenhouse in Merzhausen, Germany, in 1999. Shading, black-out, by black cloth was applied from Sep. 1, 1999, on, and by mid September one plant began to develop colored bracts while the rest of plants were still green. This plant was observed and after a few weeks taken to Hillscheid for further observation and cultivation. In the summer of 2000, cuttings were taken, rooted and grown out for the trial cultivation in the fall. After discarding 20% of the plants during this first examination, the test was repeated in 2001 and 2002, and thereafter, the new characteristic proved to be uniform and stable.

Horticultural examination of the plants starting in 2001 and continuing thereafter has demonstrated that the combination of characteristics as herein disclosed for ‘Fismillerl’ are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fismillerl’, which in combination distinguish this Poinsettia as a new and distinct cultivar:

1. uniform, red bract color;

2. medium to large sized inflorescence, ovate bracts;

3. uniform dark-green foliage, ovate leaves almost without lobes;

4. medium sized, rounded plant habit; and

5. very early flowering response.

Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Fismillerl’ is the parental cultivar ‘Fismille’. In comparison to ‘Fismille’, ‘Fismillerl’ has a shorter flowering response and can be marketed 7-10 days earlier due to earlier coloring of the bracts. Colored bracts begin developing already along the upper part of the branch, not only at the end of the branch. There is practically no difference with respect to maturing of the cyathia, however. As a consequence of earlier flowering, plants of ‘Fismillerl’ may remain somewhat smaller in size than plants of ‘Fismille’ grown under the same cultivation regime. Furthermore, it appears that ‘Fismillerl’ develops stronger branches than ‘Fismille’.

‘Fismillerl’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day-length.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographic drawing shows typical inflorescence and foliage of ‘Fismillerl’, with colors being as true as possible with illustrations of this type. The photograph shows a mature potted plant of ‘Fismillerl’ in its entirety featuring the uniform red bract color and dark-green foliage.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and comparisons describe plants grown in a greenhouse in Langley, British Columbia, Canada, in the fall of 2003. Rooted cuttings were planted into 6 inch (15 cm) pots on July 14, and were pinched on August 5, leaving 7-8 leaves. Short-day conditions were created by applying black cloth beginning September 19. The minimum temperature was initially about 20° C., from October through November only 18-19° C.

Observations and measurements were mainly taken on November 17, when the plants were in full flower and about 18 weeks old. In the following description color references are made to The Royal Horticultural Society Colour Chart (RHS). The color values were determined indoors in a North light.
